I like the running lead setup on some waters , but wouldn't dream of using it up Horseshoe where it can be very weedy . The last thing you need is the lead staying in one place as the fish moves off getting all weeded up & creating a second pivot point .
I've caught some good fish on running leads so the hooking potential is very good but I personally don't use light leads in conjunction with it 2 3/4 oz minimum as you want the lead to stay still on the pick up .
Will this be when your river fishing? Much of a current?
